Embodiment 1
[0084] Soil purification
[0085] This example outlines some implementations for decontaminating soil. supply figure 1 The device of the described embodiment, and use the crawler drill to rotate the first end of the sleeve of the device into the soil. The valve is open during insertion of the device. Insert the sleeve into the soil until the second end of the sleeve is nearly level with the soil. The valve is then closed, thereby confining a volume of soil in the channel. Inject cleaning fluid into the sleeve to chelate the metal. The sleeve is then agitated at a frequency of 1 Hz at an acceleration of 40 Gal to help remove contaminants from the soil particles. The sleeve is then agitated at a frequency of 2 Hz under an acceleration of 80 Gal to induce liquefaction and cause the cleaning fluid to rise to the top of the sleeve above the soil surface along with at least a portion of the metal contaminants present in the collected soil. The cleaning fluid is then collected ...
Embodiment 2
[0087] Purification of soil
[0088] This example outlines a method of reducing the amount of cleaning fluid that leaks into large dirt areas. The device includes a sleeve including a first opening at a first end of the sleeve and a second opening at a second end of the sleeve. The sleeve includes a valve configured to open and close the first opening. The valve is open during insertion of the device. Insert the sleeve into the soil. The valve is then closed and a certain amount of dirt is collected in the sleeve. A cleaning material (solid, liquid, gas or plasma) is then added to the material in the sleeve. The sleeve is then agitated at 0.5 Hz at an acceleration of 40 Gal to help separate contaminants from the soil. The sleeve is then left to allow the soil to settle and the cleaning fluid to rise to the top of the sleeve along with at least a portion of the contaminants present in the collected soil. The cleaning fluid, along with any contaminants contained therein, i...
Embodiment 3
[0090] sand cleaning
[0091] This example outlines some implementations for decontaminating sand. Insert the sleeve defining the inner space into the sand. The sleeve has a valve at the lower end which is open during insertion and closes once insertion is complete, providing a volume of sand in the sleeve relatively isolated from the surrounding mass of sand. Pour the oil-handling cleaning solution into the contained sand. The sleeve is then agitated at a frequency of 1 Hz at an acceleration of 30 Gal to help remove contaminants from the soil particles. The sleeve is then agitated at a frequency of 2 Hz at an acceleration of 90 Gal to induce liquefaction and lift the cleaning fluid to the top of the sleeve above the sand surface along with at least a portion of the oil contamination present in the collected sand. The cleaning fluid is then collected through the second opening along with any oil contamination contained therein. At least 25% of the cleaning fluid injected i...
